I recently purchased lyf’s flame 8 smartphone with volte 4G price 4200/-. After using 10 days, still I am not able to use internet like others. I have listened a lot about jio. But this phone runs only with jio. The internet speed is very slow with jio sim. I am using this phone with wifi. If you want to use airtel in this phone along with jio. You got only 2G network or that time your jio sim not work at all. I have complaint about it. No benefits.
